In this thesis the tortional-flexural response of a two-dimensional airfoil to forced oscillations of various frequencies and at various airspeeds is investigated. The airfoil chosen has characteristics which are typical ...

A test method is developed for evaluating the
Impact Endurance Limit of a material. The Impact
Endurance Limit is defined as the energy per blow in
tensile impact loading below which the specimen will
withstand an ...

In an endeavor to evaluate the Tension Impact Test and to correlate results, it was necessary to conduct the test upon material whose exact physical properties were known. It was decided to employ the purpose as a complete ...

Various tests have been conducted on airplane wind
tunnel models with an operating propeller in an endeavor to
furnish the industry data as an aid in design and performance
predictions. At the GALCIT, these investigations ...
